Bench Grinder Vs Angle Grinder


Bench Grinders and Angle Grinders perform many similar functions; both of them are mainly a repairman’s right-hand tool as they are indispensable. Despite both of them being grinder, they differ in their shape, usage, versatility, and many more attributes.

Throughout this article, I will identify the main differences between the two tools to further enhance your knowledge about them.


These two tools are very different in shape, as the Bench Grinder is large and weighs much more than the Angle Grinder. The Bench Grinder contains two spinning wheels on both sides that are connected by the motor between them.

On the other hand, the Angle Grinder consists of a single wheel and extended handle with a downward grip. It is light as it can weigh no more than 7 or 10 pounds. It has a grip where you can hold with your dominant hand for better control.


The fact that the Bench Grinder is heavy makes it very hard to move around, so this makes it mostly a tool that stays fixed in its place. This means that you cannot control a Bench Grinder, but you can manage your workplace around it.

The Angle Grinder is very versatile due to its lightweight, and it can be easily moved from one place to another, thus making it very easy to control.


Both users require professional hands, as injuries sustained from anyone of them can be quite harmful.

However, it is the Bench Grinder that is usually available at workshops, Woodworkers mainly use Bench Grinders to polish and renew their woodworking tools. Homeowners rarely have or use Bench Grinders.

On the contrary, Angle grinders are more common in households due to their small size and weight, as well as their ability to be moved around to cut different materials ranging from wood to steel.

Wheel Speed

The wheels of Bench Grinders and Angle Grinders are very different from each other in many aspects. They are different in their size as the wheels of Bench Grinders are wider than those o Angle Grinders.

This may be the leading reason to the face that the wheels of an Angle Grinder are much quicker than those of a Bench Grinder.

RPM (Rotations per Minute) is used to measure the speed of these two different Grinders. Concerning Bench Grinders, they usually generate around 1700 to 1900 RPM (in the case of slow Bench Grinders) or from 3000 to 3500 RPM (in the case of fast bench Grinders). However, Angle grinders usually generate around 8000 to 12000 RPM.


Despite the tools being both grinders, there are some differences that appear when they are used. These differences originate from the fact that the Bench Grinder is a stationary tool that means that it cannot be moved around, while the Angle Grinder is a portable and versatile tool that can be easily controlled.

The Bench Grinder is mostly used for polishing and sharpening your tools. A Bench Grinder can be used to quickly shape your tool in the way you want either by sharpening parts and not sharpening the others or sharpening the whole tool. Moreover, having multiple grit stones within your Bench Grinder makes it a lot easier to sharpen tools from the same set.

Angle Grinders are the perfect tool for cutting due to their smaller size and portability; they are great when it comes to cutting wood and metal.

There are also many uses for an Angle Grinder as it can be used to remove mortar from old bricks (but you need to be wary of the dust) as well as sharpening the edges of specific tools.

An Angle Grinder can also be used to clean dust from old pieces of metal, a certain type of brush will be installed on the Angle Grinder, and the piece of metal, whether it is a garden tool or a blade secured in its place and the cleaning can start.


This is the point where both Grinders meet. When using any type of grinder, your safety must be your number when priority. You should look at all times where the appropriate safety gear to protect your fingers from injuries and protect your eyes and body from the sparks. Safety Gloves and Safety Google should be worn at all times during usage of both the Bench Grinder and the Angle Grinder.

Final Thoughts

Finally, Bench grinders and Angel Grinders are two different tools, they may be the same in minor things, but their usage weight and compatibility are very different. Therefore, it is up to you to decide what are the specific properties that fit your requirements perfectly and purchase your designated tool based on these requirements.
